This invention relates to compressor outfits, and more particularly to the water cooling system for the compressor and the driving engine therefor.

The compressor outfit herein shown is of the portable type and comprises generally a V-type compressor having jacketed cylinders, an internal combustion engine also provided with jacketed cylinders, and a radiator, there being improved piping connections between the several elements. In a V-type compressor as herein disclosed it is desirable to maintain each block of cylinders at substantially the same temperature and to accomplish this I feed water to and discharge the same from the cylinder blocks in parallelism, so-tospeak.

My improved arrangement of parts is also particularly applicable to a portable type of compressor for it permits a very compact and symmetrical arrangement of the pipes. I

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in. practice.

In these drawings,

Fig. 1 is a side elevation of the portable compressor partly broken away to show th details of construction. 1

Fig. 2 is a plan view thereof with the to for the compressor outfit removed.

In the illustrative embodiment of my invention I have shown a portable compressor outfit having a wheel supported frame 1 carrying a compressor provided with cylinder blocks 2 and 3 arranged in a V-shaped manner upon a crank case 4:. Driving mechanism for the compressor comprises preferably an in.- ternal combustion engine 5 connected in' any usual manner with the compressor crankwardly to discharge water into the top of the radiator 6. This discharge 9 preferably has a flange which is bolted to the engine cylinder and to adapt the same to my lmproved I common return water pipe 18 as by Ts 19 and 20 respectively. The. pipe 18 communicates at one end with the top of the radiator 6, and at its other end is provided with a cap 21. In order to adjust and support the pipe 18, a suitable nut and screw connection 22 co operates with an upstanding top supporting member 23 carried by the frame 1. A top 24 is'supported upon the frame 23 and the radiator 6. The pipe 18 is disposed beneath and covered by the top 24. In operation thp pump 8 will be actuated to pump water from the bottom of the radiator up through the engine cylinder water jackets, through the hose 10, from which the. water will branch equally into the two compressor cylinder blocks. Due to this branch connection the temperature of the cooling water in each block will be substantially the same; and accordingly the compressed air as discharged from the con 1- pressor will have a substantially uniform temperature.- The water discharge from the compressor cylinder blocks will then merge in the pipe 18 and 'flow back to the radiator to be cooled.

While I have in this application specifical- 1y described one form which my invention may assume in practice, it will be understood'that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.

What I claim as new and desire to secure by Letters ,Patent is:

I said englne', means for conducting cooling water therefrom to the jackets for said compressor cylinders including a member having communication with the jacket for said engine cylinder at a central point and providing a conduit extending therefrom substan- 'tially longitudinally of said engine, and branch pipes leading from said'conduit and entering the jackets vfor said compressor v cylinders, and means for receiving the discharged water from the jackets for said compressor cylinders.

2. In combination, a V-type compressor having cylinders provided with cooling fluid chambers, arr-internal combustion engine for driving the same'iand also provided with a cooling fluid chamber, a source of supply for the cooling fluid, and means for circulating the cooling fluid from said source to the cooling fluid chamber for. said engine and-therefrom in parallelism through said compressor cylinder chambers.

j '3. In combination, a V-type compressor having cylinders provided with cooling fluid chambers, an internal combustion engine for driving the same and also provided with a I and above said portable compressor with an intermediate portion thereof directly over: lying the compressor, and a supporting member for one end of said pipe extending upwardly from said frame, the other end of said pipe being supported by-said radiator.

6. A- portable compressor outfit comprising a frame, a compressor cylinder thereon provided with cooling water jacket-means, a radiator at one end of said frame, means for circulating water in a closed circuit for cool-.

pressor, and a supporting member for one end" of said pipe extending upwardly from said frame, the other end of said pipe being supported by said radiator. In testimony whereof I aflix my signature.
